Bean sprouts cultivating system capable spraying water uniformly and adjusting pressures upon the bean sprouts flexibly

ABSTRACT

A bean sprouts cultivating system capable spraying water uniformly and adjusting pressures upon the bean sprouts flexibly is disclosed. An upper and a lower ends of each conduit has a water inlet and a water dropping opening, respectively. When the water flow of a water source in the water feeding system is larger than the total flow of the conduits at a bottom of the cultivation box; a downward water pressure will generate so that water will guide into the water inlet; and then water in the water dropping openings flows into the lower cultivation box uniformly. Then the water flows through the water dispatching holes in the pressure cover to more uniformly drop to the bean sprouts in the lattice disk. The surplus water will flow into the lower cultivation box from water dropping openings of the conduits.

FIELD OF THE INVENTION

[0001] The present invention relates to a bean sprouts cultivating system, and particularly to a bean sprouts cultivating system capable spraying water uniformly and adjusting pressures upon the bean sprouts flexibly.

BACKGROUND OF THE INVENTION

[0002] In the current bean sprout cultivating system, water is sprayed upon bean sprouts. To produce high quality bean sprouts and prevent bean sprouts from rotting, various chemicals are used to improve the growth of the bean sprouts. Moreover, manmade polyester is added in the air. However, this way for cultivating bean sprouts very possibly deteriorates the quality of the bean sprouts. Recently, some organic cultivating technologies are developed. However, these technologies are not completely mature. Many problems are necessary to be improved, such as complicated multi-layer water supply pipes, expensive control elements, and siphon elements which are difficult to be washed, and moreover, additives are needed.

[0003] Taiwan Patent No. 167424 “Quick Cultivating Bean Sprouts System and Water Saving System Having a Function of Automatic Level Balance”, assigned to the Applicant of the present invention. In this disclosure, the prior art bean sprout cultivating system is improved as a three dimensional cultivating system. Thereby, water can be uniformly distributed to every cultivation box. However, the water supply system of this prior art cannot effectively distributing water uniformly and further the system is complicated.

SUMMARY OF THE INVENTION

[0004] Accordingly, the primary object of the present invention is to provide a bean sprout cultivating system capable spraying water uniformly and adjusting pressures upon the bean sprouts flexibly, wherein a bottom of a cultivation box has a plurality of conduits. An upper and an lower ends of each conduit has a water inlet and a water dropping opening, respectively. When the water flow of a water source from the water feeding system is larger than the total flow of the conduits at a bottom of the cultivation box. A downward water pressure will generate so that water will guide into the water inlet; and then water in the water dropping openings flows into the lower cultivation box uniformly. Then the water flows through the water dispatching holes in the pressure cover to more uniformly drop to the bean sprouts in the lattice disk. The surplus water will flow into the lower cultivation box from water dropping openings of the conduits. After water has been supplied, the water inlets with a predetermined height installed in the conduits will sustain water of a predetermined height for being absorbed by the root of the bean sprouts. When water has reached to the cultivation box of the lowest layer; the surplus water will drain to the lower water exhausting groove from the water dropping openings of the conduits; and then the water is exhausted or reprocessed for being further used.

[0005] Another object of the present invention is to provide a bean sprout cultivating system capable spraying water uniformly and adjusting pressures upon the bean sprouts flexibly, wherein the conduit has a water inlet with a predetermined height, and the water inlets of the conduits will retain a little water which is sufficient to be absorbed by roots of the bean sprouts.

[0006] Another object of the present invention is to provide a bean sprout cultivating system capable spraying water uniformly and adjusting pressures upon the bean sprouts flexibly, wherein in the growth process of the bean sprouts, hooks at the lower sides of the two inner walls of the cultivation box and the retaining seat at the two lateral walls of the position block are installed with an elastic pressure adjusting structure formed by the belt. From the initial to the final time of the growth time of the bean sprouts, a gradually increasing elastic pressure coefficient which is derived from a result of calculation is applied (at initial time, 250 gram of bean seeds under a pressure of 1.5 kg, and at the final time, 250 gram of bean seeds under a pressure of 15 kg). Under this gradually increasing pressure, the bean sprouts will release a larger amount of ethylene stress so that the bean sprouts will growth uniformly and rapidly. Thereby, the longitudinal growth of the cells of the bean sprouts will be suppressed effectively and the transversal expansion of the cells is increased. Moreover, since the bean sprouts 81 are pressed by a continuously increasing force, a larger amount of ethylene stress metabolizes into ethylene monooxygenase and then converts into ethylene oxide. Ethylene oxide is helpful to suppress the growth and breeding of bacteria in the growth of bean sprouts. Thereby, a cultivating process of zero additive is achieved.

[0007] A further object of the present invention is to provide a bean sprouts cultivating system capable spraying water uniformly and adjusting pressures upon the bean sprouts flexibly, wherein in picking the bean sprouts, by the lattice frame of the lattice disk, the bean sprouts can be cut easily so to separate from the root of the bean sprouts. Not only the bean sprouts have delicious feeling, but also the worth of the product can be improved.

[0008] The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS. 1, 1 a, 1 b, 1 c, 1 d, 1 e, 2 and 4. It is illustrated that the present invention comprises the following components.

[0028] Cultivation boxes 1 have a structure which can be stacked over one another. The edge of the opening of the box is installed with a plurality of idle-proof positioning groove 11. The lower edge at the bottom has a plurality of idle-proof positioning pins 12 for positioning the plurality of layers. The lower edge of the internal of the box has a plurality of blocks 14 of equal height. A pair of opposite sides have recesses 18. The lower edge of each recess 18 has two hooks 13 for hooking an elastic belt 4. The bottom of the cultivation box 1 has a plurality of conduits 15. An upper and a lower ends of each conduit 15 has a water inlet 16 and a water dropping opening 17, respectively.

[0029] A pressure cover 3 likes a frame and the internal thereof is formed by a plurality of enhancing ribs 31 which are arranged with equal spaces to be like a lattice and are integrally formed. The bottom of the lattice has a plurality of water dispatching holes 32 for dispatching water uniformly. The pressure cover 3 has a retaining seat 33 at a lateral side of the recess 18 for retaining the elastic belts 4 (which may be made of rubbers with proper elasticity or a telescopic spring with a proper elasticity). The retaining seat 33 has a protecting piece 34 which is enhanced and has a plate-like shape.

[0030] A lattice disk 2 serves for bedding bean seeds. The bottom thereof is formed as a flat porous bedding net 21 which is arranged symmetrically with the lattice of the pressure cover 3. The height of the lattice frame 22 of the bedding net 21 is the height of the expanding bean seeds 8 to be cultivated. In picking, the bean sprouts 81 can resists against the lattice frame and then the roots of the bean sprouts 81 are cut. The net holes 23 of the bedding net 21 must be smaller than the bean seeds 8 so as to prevent the bean seeds 8 from falling down. The roots of the bean sprouts 81 pass through the net holes 23 for absorbing water.

[0031] An engaging and disengaging means 5 serves for engaging and disengaging the elastic belt 4. The engaging and disengaging means 5 has a control rod 51 and a biforked plate 52. The biforked plate 52 has two sub-plates each having a positioned groove 53 and a releasing arc portion 54. The groove 53 serves to resist against the belt 4 buckled to the retaining seat 33 of the pressure cover 3, as illustrated in FIGS. 3a and 3 b. Thereby, the belt 4 can slide into the hooks 13 for being buckled therein. The engaging and disengaging means 5 may be designed as an automatic machine.

[0032] A water feeding system 6 serves for supplying water and feeding water into an uppermost cultivation box.

[0033] With reference to FIGS. 5, 5a, 6, 6 a, 7, 7 a and 8, when the water flow of the water source 7 from the water feeding system 6 is larger than the total flow of the conduits 15 at the bottom of the cultivation box 1, a downward water pressure generates so that water 7 is guided to the water inlet 16. Then water in the downward protruding water dropping openings 17 flows into the lower cultivation box 1 uniformly. Then the water flows through the water dispatching holes 32 in the pressure cover 3 and thus the water can more uniformly drop to the bean sprouts 81 in the lattice disk 2. The surplus water 7 will flow into the lower cultivation box 1 from water dropping openings 17 of the conduits 15. After water has been supplied, the water inlets 16 with a predetermined height installed in the conduits 15 will sustain water of a predetermined height for being absorbed by the root of the bean sprouts 81. When water has reached to the cultivation box 1 of the lowest layer; the surplus water will drain to the lower water exhausting groove 19 from the water dropping openings 17 of the conduits 15.

[0034] In the growth process of the bean sprouts 81, in the present invention, the hooks 13 at the lower sides of the two inner walls of the cultivation box 1 and the retaining seat 33 at the two lateral walls of the position block 13 are installed with an elastic pressure adjusting structure formed by the belt 4. From the initial to the final time of the growth time of the bean sprouts 81, a gradually increasing elastic pressure coefficient which is derived from a result of calculation is applied (at initial time, 250 gram of bean seeds under a pressure of 1.5 kg, and at the final time, 250 gram of bean seeds under a pressure of 15 kg). Under this gradually increasing pressure, the bean sprouts will release a larger amount of ethylene stress so that the bean sprouts will growth uniformly and rapidly. Thereby, the longitudinal growth of the cells of the bean sprouts 81 will be suppressed effectively and the transversal expansion of the cells is increased. Moreover, since the bean sprouts 81 are pressed by a continuously increasing force, a larger amount of ethylene stress metabolizes into ethylene monooxygenase and then converts into ethylene oxide. Ethylene oxide is helpful to suppress the growth and breeding of bacteria in the growth of bean sprouts. Thereby, a cultivating process of zero additive is achieved.

[0035] When the bean sprouts 81 grows to a predetermined height capable of being gathered, the engaging and disengaging means 5 will rotate through 180 degrees. In the process of lowering the engaging and disengaging means 5, the arc portion 54 will be released to contact the belt 4, as shown in FIG. 9a. Then, due to the special design of the arc portion 54, the belt 4 will separate from the hooks 13, as shown in FIG. 9b. Therefore, the process of separation the cultivation box 1 is complete.

[0036] With reference to FIG. 10, in picking the bean sprouts 81, by the lattice frame 22 of the lattice disk 2, the bean sprouts 81 can be cut easily so separate from the root of the bean sprouts 81. Not only the bean sprouts 81 have delicious feeling, but also the worth of the product can be improved.
